Features:

Time Saver:
The Thermo-Regulator provides quick adjustment to any desired control point, within the range of the temperature scale. The resetting is easily done by the mere turning of the adjustment collar.

Sensitivity:
The Thermo-Regulator is sensitive to extremely small changes in temperature due in part to a patented feature of the adjustment electrodes.

Hermetically Sealed:
The contacts are sealed in an inert atmosphere (Hydrogen gas under high pressure.) There is no danger of corrosion. It is dust tight.

Our Sensitive Relays #MR-41 Series should be used with all our Thermostatic Controls.

Did you know?
The advances in thermometry in the first half of the eighteenth century included the significant work of Guillaume Amontons (d. 1705) on gases. He studied the expansion of gases on heating but did not achieve formulation of Charles' Law. He developed the air thermometer, which measures the increase in pressure of a system of constant volume when the temperature increases, and also made significant studies of the liquid-in-glass thermometer. The liquids used in a thermometer by Amontons, and still used today, are alcohol (with red dye in it, used at low temperatures), linseed oil (for higher temperatures), water, and mercury.
